Problems with .deb signatures

[David A. Cobb]

Well !   After 3 months of tweaking this then tweaking that I suddenly 
got the right combination and my internet connection is now working from 
Debian.  I did several updates, couldn't get things quite stable. 
That's stable only in the sense that aptitude actually completes its 
list of things to do.  There are always things that don't get
done and so are still highlighted for update.
Commented out SOURCES.LIST references to 'sid' ('unstable') & tried 
--dist-upgrade.

Now every run of APT-GET --INSTALL gets stopped by this --

Has anyone an idea of what might be happening?
TIA
